Pneumatic in-mold lid closing apparatus

An injection molding system, comprising:

• a first mold plate defining a mold cavity;
• a second mold plate opposing the first mold plate;
• and
• an in-mold lid closing apparatus coupled to the second mold plate, the in-mold lid closing apparatus comprising:
• a frame,
• a first actuation assembly configured to linearly position a lid engagement member between a first linear position and a second linear position relative to an in-mold lid, the first actuation assembly comprising:
• a first support moveably coupled to the frame, and
• a first actuator coupled to a frame support of the frame and having a first actuator drive element coupled to the first support, and
• a second actuation assembly configured to rotatably position the lid engagement member between a first rotational position and a second rotational position relative to the in-mold lid, the second actuation assembly comprising:
• a second support moveably coupled to the frame and disposed between the frame support and the first support, and
• a second actuator coupled to the second support and extending from the second support through an opening defined by the frame support and having a second actuator drive element coupled to the first support.
